These keyboards are rubber-domes, right?
I'm pretty sure only the AT101's are mechanical, but the heck do I know.

I'm not sure about that SKU model number, but there are Silicon Graphic ALPS boards out there (http://www.clickykeyboards.com/index.cfm/fa/items.main/parentcat/20188/subcatid/0/id/246624).

Yes, that one is a rubber dome keyboard, manufactured by NMB.

You had posted a picture of a KeyTronic in a Swedish layout earlier. I have got one of these in Swedish layout, if you are interested ...
It has got a key travel of 3.5 mm. Low resistance, but distinct when you bottom out.
Curved steel back plane with all keys the same size.
However, the keys rattle, and this rattling is quite loud even though the keys are otherwise quite stable. The front edge of the space bar also gets in the way a bit.

No thanks, I'm looking for a mechanical right now.

There are also non-PS/2 SGI Alps keyboards out there.

The catch? They use the same connector as the PS/2, but if you mix them up, bad things happen.

Those are pretty easy to spot though. what it looks like (http://storage.g-lenerz.de/images/sgistuff/key_indigo.jpg) (well if you have a decent picture of it lol)

Annoying thing is there was a regular PS/2 one which was also beige here (http://img.photobucket.com/albums/v104/enthauptet/bin/dell_sgi.jpg)

I think there was a granite version of those too?

Either way, you can tell them apart because the Indigo one has a flat surface, whereas the later AT-101 one is curved.

Can always check part number though...
